public void reset()
           throws TransformerException

Description copied from class: Outputter

Synchronize the state of the Outputter with that of the underlying Emitter

Specified by:

reset in class Outputter

Throws:

TransformerException

getOutputProperties

public java.util.Properties getOutputProperties()

Specified by:

getOutputProperties in class Outputter

write

public void write(java.lang.String s)
           throws TransformerException

Description copied from class: Outputter

Produce literal output. This is written as is, without any escaping. The method is provided for Java applications that wish to output literal HTML text. It is not used by the XSL system, which always writes using specific methods such as writeStartTag().

Specified by:

write in class Outputter

Throws:

TransformerException

writeContent

public void writeContent(java.lang.String s)
                  throws TransformerException

Produce text content output.
Special characters are escaped using XML/HTML conventions if the output format requires it.

Specified by:

writeContent in class Outputter

Parameters:

s - The String to be output

Throws:

TransformerException - for any failure

writeContent

public void writeContent(char[] chars,
                         int start,
                         int length)
                  throws TransformerException

Produce text content output.
Special characters are escaped using XML/HTML conventions if the output format requires it.

Specified by:

writeContent in class Outputter

Parameters:

chars - Character array to be output

start - start position of characters to be output

length - number of characters to be output

Throws:

TransformerException - for any failure

writeContent

public void writeContent(java.lang.StringBuffer chars,
                         int start,
                         int len)
                  throws TransformerException

Produce text content output.
Special characters are escaped using XML/HTML conventions if the output format requires it.

Parameters:

chars - StringBuffer containing to be output

start - start position of characters to be output

len - number of characters to be output

Throws:

TransformerException - for any failure

writeStartTag

public void writeStartTag(int nameCode)
                   throws TransformerException

Output an element start tag.
The actual output of the tag is deferred until all attributes have been output using writeAttribute().

Specified by:

writeStartTag in class Outputter

Parameters:

nameCode - The element name code

Throws:

TransformerException

checkAttributePrefix

public int checkAttributePrefix(int nameCode)
                         throws TransformerException

Check that the prefix for an attribute is acceptable, returning a substitute prefix if not. The prefix is acceptable unless a namespace declaration has been written that assignes this prefix to a different namespace URI. This method also checks that the attribute namespace has been declared, and declares it if not.

Specified by:

checkAttributePrefix in class Outputter

Throws:

TransformerException

writeNamespaceDeclaration

public void writeNamespaceDeclaration(int nscode)
                               throws TransformerException

Output a namespace declaration.
This is added to a list of pending namespaces for the current start tag. If there is already another declaration of the same prefix, this one is ignored. Note that unlike SAX2 startPrefixMapping(), this call is made AFTER writing the start tag.

Specified by:

writeNamespaceDeclaration in class Outputter

Parameters:

nscode - The namespace code

Throws:

TransformerException - if there is no start tag to write to (created using writeStartTag), or if character content has been written since the start tag was written.

copyNamespaceNode

public void copyNamespaceNode(int nscode)
                       throws TransformerException

Copy a namespace node to the current element node (Rules defined in XSLT 1.0 errata)

Specified by:

copyNamespaceNode in class Outputter

Throws:

TransformerException

thereIsAnOpenStartTag

public boolean thereIsAnOpenStartTag()

Test whether there is an open start tag. This determines whether it is possible to write an attribute node at this point.

Specified by:

thereIsAnOpenStartTag in class Outputter

writeAttribute

public void writeAttribute(int nameCode,
                           java.lang.String value)
                    throws TransformerException

Output an attribute value.
This is added to a list of pending attributes for the current start tag, overwriting any previous attribute with the same name.
This method should NOT be used to output namespace declarations.

Overrides:

writeAttribute in class Outputter

Parameters:

nameCode - The name code of the attribute

value - The value of the attribute

Throws:

TransformerException - if there is no start tag to write to (created using writeStartTag), or if character content has been written since the start tag was written.

writeAttribute

public void writeAttribute(int nameCode,
                           java.lang.String value,
                           boolean noEscape)
                    throws TransformerException

Output an attribute value.
This is added to a list of pending attributes for the current start tag, overwriting any previous attribute with the same name.
This method should NOT be used to output namespace declarations.
Before calling this, checkAttributePrefix() should be called to ensure the namespace is OK.

Specified by:

writeAttribute in class Outputter

Parameters:

value - The value of the attribute

noEscape - True if it's known there are no special characters in the value. If unsure, set this to false.

Throws:

TransformerException - if there is no start tag to write to (created using writeStartTag), or if character content has been written since the start tag was written.

writeEndTag

public void writeEndTag(int nameCode)
                 throws TransformerException

Output an element end tag.

Specified by:

writeEndTag in class Outputter

Parameters:

nameCode - The element name code

Throws:

TransformerException

writeComment

public void writeComment(java.lang.String comment)
                  throws TransformerException

Specified by:

writeComment in class Outputter

Throws:

TransformerException
