Method Detail

clone

public java.lang.Object clone()

Clones the array initializer

Specified by:

clone in interface JmlExpression

Overrides:

clone in class Statement

Returns:

hte cloned array initializer

equals

public boolean equals(Expression e)

Description copied from class: Expression

Returns whether two expressions are equal.

Specified by:

equals in class Expression

Parameters:

e - The tested expression

Returns:

true if the expression equals the parameter, false otherwise

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.

toJava

public java.lang.String toJava(int indent)

Description copied from class: Expression

Displays the expression corresponding to a part of a method specification in a tool tip with the initial Java syntax.

Specified by:

toJava in class Expression

Returns:

the string corresponding to this expression

Throws:

java.lang.InternalError - since an array initializer appears only in expression with side effects.

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:

the link info resulting from the link

Throws:

Jml2bException

typeCheck

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

Throws:

Jml2bException

processIdent

public void processIdent()

Description copied from class: Expression

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.

Specified by:

processIdent in class Expression

Specified by:

subResult in class Expression

isModifiersCompatible

public void isModifiersCompatible(Modifiers modifiers)

Description copied from class: Expression

Tests whether the expression contains fields that have modifiers compatible with the invariant modifiers.

• If the invariant is static, all fields should be static.
• If the invariant is private, all fields should be private.
• If the invariant is package-visible, all fields should be almost package-visible.
• If the invariant is protected, all fields should be almost protected.

Specified by:

isModifiersCompatible in class Expression

Parameters:

modifiers - The current invariant modifiers

Throws:
