Constructs a sequence from another one.

Parameters:

pi - The parsed item

left - The first statement

right - The second statement

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,

                       throws Jml2bException

Description copied from class: Statement

Links the statement.

Specified by:

linkStatement in class Statement

Returns:

the link info resulting from the link

Throws:

Jml2bException

typeCheck

public Type typeCheck(IJml2bConfiguration config,
                      LinkContext f)
               throws Jml2bException

                       throws PogException

Description copied from class: Statement

Collects all the indentifier of the statement to give them an index in the identifer array. This array is then analyzed to give short name when it is possible to identifiers. Instancie the statement. More informations on instancie.

Specified by:

jmlNormalize in class Statement

Parameters:

definingClass - The class where this statement is defined

Returns:

the normalized statement

Throws:

public Statement firstStatement()

Description copied from class: Statement

Returns the first statement in a sequence. If the statement is not a sequence, return it.

Overrides:

firstStatement in class Statement

Returns:

the first statement of the first statement

See Also:

firstStatement()

tail

public Statement tail()

Description copied from class: Statement
