Method Detail
-
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:
