Constructor Detail

StVarDecl

public StVarDecl(java.util.Vector localVariables)

Constructs a statement from a set of fields

Parameters:

localVariables - The set of fields.

Method Detail

emit

public java.lang.String emit()

Specified by:

emit in class Statement

parse

public antlr.collections.AST parse(antlr.collections.AST tree)
                            throws Jml2bException

Description copied from class: Statement

Parses an AST tree in order to instanciate the statement fields.

Specified by:

parse in class Statement

Parameters:

tree - AST tree containing the statement

Throws:

Jml2bException - when a parse error occurs.

linkStatement

public LinkInfo linkStatement(IJml2bConfiguration config,
                              LinkContext f)
                       throws Jml2bException

Description copied from class: Statement

Links the statement.

Specified by:

linkStatement in class Statement

Returns:
