Constructor Detail

VariableDeclaration

VariableDeclaration()

Constructor for serialization.

VariableDeclaration

public VariableDeclaration(java.lang.String name,
                           TypeDescriptor<?> type)

Creates a new variable declaration. Parent must be explicitly adjusted by parent instance.

Parameters:

name - the name of the variable

type - the type of the variable

VariableDeclaration

public VariableDeclaration(java.lang.String name,
                           TypeDescriptor<?> type,
                           boolean isConstant,
                           Expression expression)

Creates a new variable declaration.

Parameters:

name - the name of the variable

type - the type of the variable

isConstant - whether this variable is a constant

expression - an expression denoting the initial value (may be null)

Method Detail

accept

public java.lang.Object accept(IVisitor visitor)
                        throws VilException

Description copied from interface: ITemplateLangElement

Accepts the visitor for visiting.

Specified by:

accept in interface ITemplateLangElement

Parameters:

visitor - the visitor to be used

Returns:

the result of visiting this instance (may be null)

Throws:

VilException - in case that visiting fails (e.g., execution)

isLoop

public boolean isLoop()

Description copied from interface: ITemplateElement

Returns whether this element is a loop.

Specified by:

isLoop in interface ITemplateElement

Returns:

true if it is a loop, false else

isBlock

public boolean isBlock()

Description copied from interface: ITemplateElement

Returns whether this element is a block (opposite is a single statement).

Specified by:

isBlock in interface ITemplateElement

Returns:

true if it is a block, false else

inferType

public TypeDescriptor<?> inferType()
                            throws VilException

Description copied from interface: ITemplateElement

Infers the type of this language element.

Specified by:

inferType in interface ITemplateElement

Returns:

the type of this language element

Throws:

VilException - in case that type errors occur

getParent

public ILanguageElement getParent()

Description copied from interface: ILanguageElement

Returns the parent element.

Specified by:

getParent in interface ILanguageElement

Returns:

the parent element (may be null if unknown)

setParent

protected void setParent(ILanguageElement parent)

Changes the parent. Please override if children must be adjusted according. Shall be called only once per instance, but there is no limitation.

Parameters:

parent - the parent

endsWithContentStatement

public boolean endsWithContentStatement()

Description copied from interface: ITemplateElement

Returns whether this element ends with a content statement.

Specified by:

endsWithContentStatement in interface ITemplateElement

Returns:
