OneOf

public OneOf(String propertyNameOrExpression,
 boolean ignoreCase,
 String... values)

Determine whether the value of a property, expressed as a String, is in the specified array of values.

Parameters:

propertyNameOrExpression - either a literal string which represents a property name, or an expression resolving to a numeric value.

ignoreCase - determines if the comparison should ignore the string case.

values - the values or expressions resolving to strings to compare with.

Method Details

accepts

public boolean accepts(PropertiesCollection<String> info)

Determines whether this policy accepts the specified node.

Specified by:

accepts in class ExecutionPolicy

Parameters:

info - system information for the node on which the tasks will run if accepted.

Returns:

true if the node is accepted, false otherwise.

Parameters:

properties - the proeprties collection to evaluate against.

Returns:

the typed value of the left operand expression.
