Constructor Summary

Constructors

Constructor	Description
NotEqual(String propertyNameOrExpression, boolean a)	Define an inequality comparison between the boolean value of a property and another boolean value.
NotEqual(String propertyNameOrExpression, boolean ignoreCase, String a)	Define an inequality comparison between the string value of a property and another string value.
NotEqual(String propertyNameOrExpression, double a)	Define an inequality comparison between the numeric value of a property and another numeric value.
NotEqual(ValueType valueType, String propertyNameOrExpression, String a)	Define an inequality comparison between the numeric value of a property and another numeric value. Note that if the value type is equal to ValueType.STRING, then the comparison will be case-insensitive.

Constructor Details

NotEqual

public NotEqual(ValueType valueType,
 String propertyNameOrExpression,
 String a)

Define an inequality comparison between the numeric value of a property and another numeric value.
Note that if the value type is equal to ValueType.STRING, then the comparison will be case-insensitive. To specify case sensitivity, use the #Equal(String, boolean, String) constructor instead.

Parameters:

valueType - the type of value to which thie equality comparison applies.

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

a - the value to compare with.

NotEqual

public NotEqual(String propertyNameOrExpression,
 double a)

Define an inequality comparison between the numeric value of a property and another numeric value.

Parameters:

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

a - the value to compare with.

NotEqual

public NotEqual(String propertyNameOrExpression,
 boolean ignoreCase,
 String a)

Define an inequality comparison between the string value of a property and another string value.

Parameters:

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

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

a - the value to compare with.

NotEqual

public NotEqual(String propertyNameOrExpression,
 boolean a)

Define an inequality comparison between the boolean value of a property and another boolean value.

Parameters:

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

a - the value to compare with.

Method Details

accepts

public boolean accepts(PropertiesCollection<String> info)

Description copied from class: Equal

Determines whether this policy accepts the specified node.

Overrides:

accepts in class Equal

Parameters:

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

Returns:

true if the node is accepted, false otherwise.

getLeftOperandValue

protected Object getLeftOperandValue(PropertiesCollection<String> properties)

Parameters:

properties - the proeprties collection to evaluate against.

Returns:

the typed value of the left operand expression.
