Method Detail

traceIn

public void traceIn(String ruleName)

Overrides:

traceIn in class antlr.LLkParser

traceOut

public void traceOut(String ruleName)

Overrides:

traceOut in class antlr.LLkParser

trace

protected void trace(String msg)

Method for logging execution trace information.

Overrides:

trace in class GeneratedOrderByFragmentParser

Parameters:

msg - The trace message.

quotedIdentifier

protected antlr.collections.AST quotedIdentifier(antlr.collections.AST ident)

Process the given node as a quote identifier. These need to be quoted in the dialect-specific way.

Overrides:

quotedIdentifier in class GeneratedOrderByFragmentParser

Parameters:

ident - The quoted-identifier node.

Returns:

The processed node.

See Also:

Dialect.quote(java.lang.String)

quotedString

protected antlr.collections.AST quotedString(antlr.collections.AST ident)

Process the given node as a quote string.

Overrides:

quotedString in class GeneratedOrderByFragmentParser

Parameters:

ident - The quoted string. This is used from within function param recognition, and represents a SQL-quoted string.

Returns:

The processed node.

isFunctionName

protected boolean isFunctionName(antlr.collections.AST ast)

A check to see if the text of the given node represents a known function name.

Overrides:

isFunctionName in class GeneratedOrderByFragmentParser

Parameters:

ast - The node whose text we want to check.

Returns:

True if the node's text is a known function name, false otherwise.

resolveFunction

protected antlr.collections.AST resolveFunction(antlr.collections.AST ast)

Process the given node as a function.

Overrides:

resolveFunction in class GeneratedOrderByFragmentParser

Returns:

The processed node.

resolveIdent

protected antlr.collections.AST resolveIdent(antlr.collections.AST ident)

Process the given node as an IDENT. May represent either a column reference or a property reference.

Overrides:

resolveIdent in class GeneratedOrderByFragmentParser

Parameters:

ident - The node whose text represents either a column or property reference.

Returns:

The processed node.

postProcessSortSpecification

protected antlr.collections.AST postProcessSortSpecification(antlr.collections.AST sortSpec)

Allow post processing of each sort specification

Overrides:

postProcessSortSpecification in class GeneratedOrderByFragmentParser

Returns:

The processed sort specification subtree.
