Direct Known Subclasses:
PseudoClassDataBinding
public class DataBinding
extends java.lang.Object
Represents a data binding in a JAXX file. DataBinding uses DataSource to track changes to a source expression and update the destination.

    • constantId

      protected java.lang.String constantId
      Constant id build from the realId and used instead of realId in generated code

    • dataSource

      protected DataSource dataSource
      Compiled data source

    • processDataBinding

      protected java.lang.String processDataBinding

      Extra method to add to the binding

  • Constructor Details

    • DataBinding

      public DataBinding​(java.lang.String id, java.lang.String source, java.lang.String assignment, boolean quickNoDependencies)
      Creates a new data binding.
      Parameters:
      id - the data binding destination in the form id.propertyName
      source - the Java source code for the data binding expression
      assignment - Java snippet which will cause the destination property to be updated with the current value of the binding
      quickNoDependencies - internal flag to not treate process databinding in not a real binding

    • compile

      public boolean compile​(JAXXCompiler compiler) throws CompilerException
      Compiles the data binding expression. This method calls methods in JAXXCompiler to add the Java code that performs the data binding setup.
      Parameters:
      compiler - compiler which includes the data binding
      Returns:
      true if the expression has dependencies, false otherwise
      Throws:
      CompilerException - if a compilation error occurs
