Detailed Description

A container for static variables defined in Templates.

This class is only relevant to Template tag authors.

When processing a template tag in a AbstractNodeFactory implementation, it will sometimes make sense to process arguments to the tag as KTextTemplate::Variables. Note that usually they should be processed as FilterExpression objects instead.

Arguments to the tag can be used to construct Variables, which may then be resolved into the objects they represent in the given Context in the render stage.

Variable::Variable ( const QString var)
explicit

Creates a Variable represented by the given var.

Definition at line 83 of file variable.cpp.

Member Function Documentation

◆ isConstant()

bool Variable::isConstant ( ) const

Returns whether this Variable is a constant in the Template.

A constant is represented as a static string in the template

Text content
{% some_tag "constant" variable %}

Definition at line 136 of file variable.cpp.

◆ isLocalized()

bool Variable::isLocalized ( ) const

Returns whether this variable is localized, that is, if it is wrapped with _().

Definition at line 147 of file variable.cpp.

◆ isTrue()

bool Variable::isTrue ( Context c) const

Returns whether this Variable evaluates to true with the Context c.

Definition at line 142 of file variable.cpp.

◆ isValid()

bool Variable::isValid ( ) const

Returns whether this Variable is valid.

Definition at line 130 of file variable.cpp.

◆ literal()

QVariant Variable::literal ( ) const

Returns whether this variable is a literal string or number.

A literal Variable does not have any lookup components.

Definition at line 153 of file variable.cpp.

◆ lookups()

QStringList Variable::lookups ( ) const

Returns the lookup components of this Variable.

Definition at line 159 of file variable.cpp.

◆ operator=()

Variable & Variable::operator= ( const Variable other)

Assignment operator.

Definition at line 72 of file variable.cpp.

◆ resolve()

QVariant Variable::resolve ( Context c) const

Resolves this Variable with the Context c.

Definition at line 174 of file variable.cpp.
