Constructor Detail

Literal

public Literal(ExtList children)

Constructor for the transformation of COMPOST ASTs to KeY.

Parameters:

children - the children of this AST element as KeY classes. May contain: Comments

Literal

public Literal()

Literal

Literal

public Literal(ExtList children,
               PositionInfo pos)

Literal with specific source code position.

Parameters:

children - the children of this AST element as KeY classes. May contain: Comments

pos - The specific source code position.

Parameters:

pos - The specific source code position.

Method Detail

getKeYJavaType

public KeYJavaType getKeYJavaType(Services javaServ,
                                  ExecutionContext ec)

retrieves the literal's type (as it is independant of the execution context, it is same as using getKeYJavaType(Services))

Specified by:

getKeYJavaType in interface Expression

Parameters:

javaServ - the Services offering access to the Java model

ec - the ExecutionContext in which the expression is evaluated

Returns:

the literal's type

getKeYJavaType

public abstract KeYJavaType getKeYJavaType(Services javaServ)

retrieves the literal's type

Parameters:

javaServ - the Services offering access to the Java model

Returns:

the literal's type

match

public MatchConditions match(SourceData source,
                             MatchConditions matchCond)

Description copied from interface: ProgramElement

matches the source "text" (@link SourceData#getSource()) against the pattern represented by this object. In case of a successful match the resulting MatchConditions with the found instantiations of the schemavariables. If the match failed, null is returned instead.

Specified by:

match in interface ProgramElement

Overrides:

match in class JavaProgramElement

Parameters:

source - the SourceData with the program element to match

matchCond - the MatchConditions found up to this point

Returns:

the resulting match conditions or null if the match failed

getLDTName

public abstract Name getLDTName()
