Method Detail

anyNull

public static boolean anyNull(java.lang.Object... objects)

Parameters:

objects - List of objects to check if any are null.

Returns:

True if any of the objects passed is null, false otherwise.

sameClass

public static boolean sameClass(java.lang.Object first,
                                java.lang.Object second)

This method checks if two objects are of the same class.

Parameters:

first - First object to check.

second - Second object to check.

Returns:

True if both have the same class, false otherwise.

sameInstance

public static boolean sameInstance(java.lang.Object first,
                                   java.lang.Object second)

This method checks if two object point to the same instance.

Parameters:

first - First object to check.

second - Second object to check.

Returns:

True if both first and second point to the same instance, false otherwise.

areEqual

public static boolean areEqual(BusinessKeyField pojoField,
                               java.lang.Object first,
                               java.lang.Object second,
                               boolean caseSensitive)

Perform Equality between two PojoFields' instances. This is different from regular equals implementation that it will return true if both fields are null, as well as it takes into account case based equality for character sequences.

Parameters:

pojoField - The pojoField to perform the equality on.

first - The first instance that contains this PojoField.

second - The second instance that contains this PojoField.

caseSensitive - Whether or not to compare ignoring case.

Returns:

True if they are equal or if they are both null.

getHashCode

public static int getHashCode(BusinessKeyField pojoField,
                              java.lang.Object instance,
                              boolean caseSensitive)

Generate HashCode on field value.

Parameters:

pojoField - The pojoField to get the hashCode for.

instance - The instance to pull the field value out of.

caseSensitive - Whether or not to ignore case while generating hash code.

Returns:

The generated HashCode.
