FrameContextImpl

public FrameContextImpl(Frame window,
                        java.util.Map<java.lang.String,java.lang.Object> params)

Method Detail

getParameterNames

public java.util.Collection<java.lang.String> getParameterNames()

getParameterValue

public <T> T getParameterValue(java.lang.String property)

getFrame

public Frame getFrame()

Specified by:

getFrame in interface FrameContext

getParams

public java.util.Map<java.lang.String,java.lang.Object> getParams()

Description copied from interface: FrameContext

For a window contains parameters passed to the window on opening.
For a frame, linked to the window in XML, contains owning window parameters.
For a frame, opened dynamically by openFrame() method contains parameters, passed to the method.

Specified by:

getParams in interface FrameContext

getParamValue

public <T> T getParamValue(java.lang.String param)

Description copied from interface: FrameContext

Value of an external parameters passed to the window on opening.

Specified by:

getParamValue in interface FrameContext

getValue

public <T> T getValue(java.lang.String property)

Description copied from interface: FrameContext

Retrieves value of a component by complex name, dereferencing path to the component and possible drill down to the value

Specified by:

getValue in interface FrameContext

Parameters:

property - path to the value. Parsed by the following rules:
First split by dots taking into account square brackets, and looking for a component from left to right.
If a component not found, return null.
If a component found and it is a Component.HasValue or ListComponent, retrieve its value.
If the value is null, return it.
If there is nothing left in the path after the component name, return the value.
Else if the value is Instance, drill down to it and return the value of the property by remaining property path.
If the value is an EnumClass and remaining property path is "id", return EnumClass.getId() value.

setValue

public void setValue(java.lang.String property,
                     java.lang.Object value)

Description copied from interface: FrameContext

Set value of a component by its path in the window

Specified by:

setValue in interface FrameContext

Parameters:

property - path to the component (separated by dots, taking into account square brackets)

value - value to set
