Constructor Detail

Text

public Text()

Create a blank Text syntax tree node.

Text

public Text(java.lang.String text)

Create text syntax tree node.

Parameters:

text - is the text to put in the node.

Method Detail

getText

protected java.lang.String getText()

Returns the text wrapped inside this node

Returns:

The text wrapped inside this node

setText

protected void setText(java.lang.String text)

Set the text for this node. Appends the given text to any already existing text (using string concatenation, so use only when needed).

Parameters:

text - is the text to wrap inside this node.

display

public void display(int indent)

Description copied from class: SyntaxTreeNode

Displays the contents of this syntax tree node (to stdout). This method is intended for debugging _only_, and should be overridden by all syntax tree node implementations.

Overrides:

display in class SyntaxTreeNode

Parameters:

indent - Indentation level for syntax tree levels.

parseContents

public void parseContents(Parser parser)

Description copied from class: SyntaxTreeNode

Parse the contents of this syntax tree nodes (child nodes, XPath expressions, patterns and functions). The default behaviour is to parser the syntax tree node's children (since there are no common expressions, patterns, etc. that can be handled in this base class.

Overrides:

parseContents in class SyntaxTreeNode

Parameters:

parser - reference to the XSLT parser

ignore

public void ignore()

isIgnore

public boolean isIgnore()

isTextElement

public boolean isTextElement()

contextDependent

protected boolean contextDependent()

Description copied from class: SyntaxTreeNode

Returns true if this expression/instruction depends on the context. By default, every expression/instruction depends on the context unless it overrides this method. Currently used to determine if result trees are compiled using procedures or little DOMs (result tree fragments).

Overrides:

contextDependent in class SyntaxTreeNode

Returns:

'true' if this node depends on the context.

isWhitespace

private static boolean isWhitespace(char c)

translate

public void translate(ClassGenerator classGen,
                      MethodGenerator methodGen)

Description copied from class: Instruction

Translate this node into JVM bytecodes.

Overrides:

translate in class Instruction

Parameters:

classGen - BCEL Java class generator

methodGen - BCEL Java method generator

canLoadAsArrayOffsetLength

public boolean canLoadAsArrayOffsetLength()

Check whether this Text node can be stored in a char[] in the translet. Calling this is precondition to calling loadAsArrayOffsetLength.

Returns:

true if this Text node can be

See Also:

loadAsArrayOffsetLength(ClassGenerator,MethodGenerator)

loadAsArrayOffsetLength

public void loadAsArrayOffsetLength(ClassGenerator classGen,
                                    MethodGenerator methodGen)

Generates code that loads the array that will contain the character data represented by this Text node, followed by the offset of the data from the start of the array, and then the length of the data. The pre-condition to calling this method is that canLoadAsArrayOffsetLength() returns true.
