public final class StringOutputter
extends Outputter

This class allows output to be generated. It channels output requests to an Emitter which does the actual writing. This is a specialized and simplified version that is used to handle xsl:attribute, xsl:comment, and xsl:processing-instruction.

Constructor Detail

StringOutputter

public StringOutputter(java.lang.StringBuffer buffer)
Method Detail

setErrorListener

public void setErrorListener(ErrorListener listener)

reset

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
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

writeStartTag

public void writeStartTag(int nameCode)
                   throws TransformerException
Output an element start tag. With this outputter, this is a recoverable error.

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,
                           boolean noEscape)
                    throws TransformerException
Output an attribute value.
No-op in this implementation.

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
Write a comment. No-op in this implementation

Specified by:
writeComment in class Outputter
Throws:
TransformerException

writePI

public void writePI(java.lang.String target,
                    java.lang.String data)
             throws TransformerException
Write a processing instruction No-op in this implementation

Specified by:
writePI in class Outputter
Throws:
TransformerException

close

public void close()
           throws TransformerException
Close the output

Specified by:
close in class Outputter
Throws:
TransformerException
