Method Detail

getName

public String getName()

Description copied from interface: JRVariable

Returns the name of the variable. Since all variables are stored in a map, the variable names are the keys in the map.

Specified by:

getName in interface JRVariable

Returns:

a string containing the variable name

getValueClass

public Class<?> getValueClass()

Description copied from interface: JRVariable

Returns the class of the variable value. Any class is allowed as long as it is in the classpath at compile and run time.

Specified by:

getValueClass in interface JRVariable

Returns:

a Class instance representing the variable value class

getValueClassName

public String getValueClassName()

Description copied from interface: JRVariable

Returns the string name of the variable value class.

Specified by:

getValueClassName in interface JRVariable

getIncrementerFactoryClass

public Class<?> getIncrementerFactoryClass()

Description copied from interface: JRVariable

Returns the class of the incrementer factory used for choosing the right incrementer for the variable value.

Specified by:

getIncrementerFactoryClass in interface JRVariable

Returns:

the Class instance of the incrementer factory

See Also:

JRIncrementer, JRIncrementerFactory

getIncrementerFactoryClassName

public String getIncrementerFactoryClassName()

Description copied from interface: JRVariable

Returns the string name of the variable value class.

Specified by:

getIncrementerFactoryClassName in interface JRVariable

getResetTypeValue

public ResetTypeEnum getResetTypeValue()

Description copied from interface: JRVariable

Gets the variable reset type.

Specified by:

getResetTypeValue in interface JRVariable

Returns:

a value representing one of the reset type constants in ResetTypeEnum

getIncrementTypeValue

public IncrementTypeEnum getIncrementTypeValue()

Description copied from interface: JRVariable

Gets the variable increment type.

Specified by:

getIncrementTypeValue in interface JRVariable

Returns:

a value representing one of the reset type constants in IncrementTypeEnum

getCalculationValue

public CalculationEnum getCalculationValue()

Description copied from interface: JRVariable

Gets the variable calculation type.

Specified by:

getCalculationValue in interface JRVariable

Returns:

a value representing one of the calculation type constants in CalculationEnum

isSystemDefined

public boolean isSystemDefined()

Description copied from interface: JRVariable

Returns true if the variable calculation type is system defined.

Specified by:

isSystemDefined in interface JRVariable

See Also:

CalculationEnum.SYSTEM

getExpression

public JRExpression getExpression()

Description copied from interface: JRVariable

Returns the main expression for this variable. The expression must be numeric for certain calculation types.

Specified by:

getExpression in interface JRVariable

Returns:

a JRExpression instance containing the expression.

getInitialValueExpression

public JRExpression getInitialValueExpression()

Description copied from interface: JRVariable

Returns the initial value expression for this variable. The expression must be numeric for certain calculation types.

Specified by:

getInitialValueExpression in interface JRVariable

Returns:

a JRExpression instance containing the initial expression.

getResetGroup

public JRGroup getResetGroup()

Description copied from interface: JRVariable

Returns the group whose break triggers the variable reset. Only used when JRVariable.getResetTypeValue() returns ResetTypeEnum.GROUP.

Specified by:

getResetGroup in interface JRVariable

getIncrementGroup

public JRGroup getIncrementGroup()

Description copied from interface: JRVariable

Returns the group whose break triggers the variable increment. Only used when JRVariable.getIncrementTypeValue() returns IncrementTypeEnum.GROUP.

Specified by:

getIncrementGroup in interface JRVariable

clone

public Object clone()

Specified by:

clone in interface JRCloneable

Overrides:

clone in class Object
