Constructor Detail
new sap.ui.model.PropertyBinding(oModel, sPath, oContext, mParameters?)
Constructor for PropertyBinding
Parameters:
{sap.ui.model.Model}oModel
{string}sPath
{sap.ui.model.Context}oContext
{object}mParameters?
Method Detail
sap.ui.model.PropertyBinding.extend(sClassName, oClassInfo?, FNMetaImpl?): function
Creates a new subclass of class sap.ui.model.PropertyBinding with name sClassName and enriches it with the information contained in oClassInfo.

oClassInfo might contain the same kind of information as described in sap.ui.model.Binding.extend.

Parameters:
{string}sClassName Name of the class being created
{object}oClassInfo? Object literal with information about the class
{function}FNMetaImpl? Constructor function for the metadata object; if not given, it defaults to sap.ui.core.ElementMetadata
Returns:
{function} Created class / constructor function
sap.ui.model.PropertyBinding.getMetadata(): sap.ui.base.Metadata
Returns a metadata object for class sap.ui.model.PropertyBinding.
Returns:
{sap.ui.base.Metadata} Metadata object describing this class
getBindingMode(): sap.ui.model.BindingMode
Returns the binding mode
Returns:
{sap.ui.model.BindingMode} the binding mode
getExternalValue(): object
Returns the current external value of the bound target which is formatted via a type or formatter function.
Exceptions:
sap.ui.model.FormatException
Returns:
{object} the current value of the bound target
getFormatter(): function
Returns the formatter function
Returns:
{function} the formatter function
getType(): sap.ui.model.Type
Returns the type if any for the binding.
Returns:
{sap.ui.model.Type} the binding type
getValue(): object
Returns the current value of the bound target
Returns:
{object} the current value of the bound target
resume()
Resumes the binding update. Change events will be fired again.

When the binding is resumed and the control value was changed in the meantime, the control value will be set to the current value from the model and a change event will be fired.

setBindingMode(sBindingMode)
Sets the binding mode
Parameters:
{sap.ui.model.BindingMode}sBindingMode the binding mode
setExternalValue(oValue)
Sets the value for this binding. The value is parsed and validated against its type and then set to the binding. A model implementation should check if the current default binding mode permits setting the binding value and if so set the new value also in the model.
Parameters:
{object}oValue the value to set for this binding
Exceptions:
sap.ui.model.ParseException
sap.ui.model.ValidateException
setFormatter(fnFormatter)
Sets the optional formatter function for the binding.
Parameters:
{function}fnFormatter the formatter function for the binding
setType(oType, sInternalType)
Sets the optional type and internal type for the binding. The type and internal type are used to do the parsing/formatting correctly. The internal type is the property type of the element which the value is formatted to.
Parameters:
{sap.ui.model.Type}oType the type for the binding
{String}sInternalType the internal type of the element property which this binding is bound against.
setValue(oValue)
Sets the value for this binding. A model implementation should check if the current default binding mode permits setting the binding value and if so set the new value also in the model.
Parameters:
{object}oValue the value to set for this binding
