Class MathTask

  • All Implemented Interfaces:
    java.lang.Cloneable

    public class MathTask
    extends org.apache.tools.ant.Task
    Provides basic math functions. Simple calculations can be done via attributes only, more complex formulas can be set up via nested Ops.

      • setResult

        public void setResult​(java.lang.String name)
        Sets the name of the property to store the result in. This is stored in a user property, so is reusable.
        Parameters:
        name - the name of a property to set for a result.
      • setDatatype

        public void setDatatype​(java.lang.String type)
        Sets the datatype of this calculation. Allowed values are "int", "long", "float", or "double". Optional, if used, will be applied to all numbers in this math operation.
      • setOperand1

        public void setOperand1​(java.lang.String op)
                         throws org.apache.tools.ant.BuildException
        Set an operand as an attribute. This is for convenience, if used, it overrides any nested Ops. Must parse to a number.
        Throws:
        org.apache.tools.ant.BuildException
      • setOperand2

        public void setOperand2​(java.lang.String op)
                         throws org.apache.tools.ant.BuildException
        Set an operand as an attribute. This is for convenience, if used, it overrides any nested Ops. Must parse to a number.
        Throws:
        org.apache.tools.ant.BuildException
      • setOperation

        public void setOperation​(java.lang.String op)
        Set an operation as an attribute. This is for convenience, if used, it overrides any nested Ops.
        Parameters:
        op - any operation allowed by Op.
      • addConfiguredOp

        public void addConfiguredOp​(Op op)
        Add a nested operation. Only one operation is allowed at a time.
        Parameters:
        op - the operation to add.
      • setStrict

        public void setStrict​(boolean b)
        Use the StrictMath library.
      • execute

        public void execute()
        Overrides:
        execute in class org.apache.tools.ant.Task
