Method Details

setNameIfUnnamed

public void setNameIfUnnamed(String name)

getName

public String getName()

Description copied from interface: Parameter

Return the parameter name, or null if the parameter is not a named parameter or no name has been assigned.

Specified by:

getName in interface Parameter<T>

Returns:

parameter name

getPosition

public Integer getPosition()

Description copied from interface: Parameter

Return the parameter position, or null if the parameter is not a positional parameter.

Specified by:

getPosition in interface Parameter<T>

Returns:

position of parameter

getParameterType

public Class<T> getParameterType()

Description copied from interface: Parameter

Return the Java type of the parameter. Values bound to the parameter must be assignable to this type. This method is required to be supported for criteria queries only. Applications that use this method for Java Persistence query language queries and native queries will not be portable.

public void setExpressionToQuery(StringBuilder query,
 CriteriaParameterFiller parameterFiller)

Specified by:

setExpressionToQuery in class AbstractExpression<T>

equals

public boolean equals(Object o)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object
