Method Detail

atLeast

public static BytesValidator atLeast(int byteLength)

Checks the length of a byte array

Parameters:

byteLength - to check against

Returns:

true if longer or equal to given value

atMost

public static BytesValidator atMost(int byteLength)

Checks the length of a byte array

Parameters:

byteLength - to check against

Returns:

true if smaller or equal to given value

exactLength

public static BytesValidator exactLength(int byteLength)

Checks the length of a byte array

Parameters:

byteLength - to check against

Returns:

true if equal to given value

onlyOf

public static BytesValidator onlyOf(byte refByte)

Checks individual byte content

Parameters:

refByte - to check against

Returns:

true if array only consists of refByte

notOnlyOf

public static BytesValidator notOnlyOf(byte refByte)

Checks individual byte content

Parameters:

refByte - to check against

Returns:

true if array has at least one byte that is not refByte

startsWith

public static BytesValidator startsWith(byte... startsWithBytes)

Checks if the internal byte array starts with given bytes

Parameters:

startsWithBytes - the supposed prefix

Returns:

true all startsWithBytes match the first bytes in the internal array

endsWith

public static BytesValidator endsWith(byte... endsWithBytes)

Checks if the internal byte array ends with given bytes

Parameters:

endsWithBytes - the supposed postfix

Returns:

true all startsWithBytes match the first bytes in the internal array

noneOf

public static BytesValidator noneOf(byte refByte)

Checks individual byte content

Parameters:

refByte - to check against

Returns:

true if array has no value refByte

or

public static BytesValidator or(BytesValidator... validators)

This will execute all passed validators and returns true if at least one returns true (i.e. OR concatenation)

Parameters:

validators - at least one validator must be passed

Returns:

true if at least one validator returns true

and

public static BytesValidator and(BytesValidator... validators)

This will execute all passed validators and returns true if all return true (i.e. AND concatenation)

Parameters:

validators - at least one validator must be passed

Returns:

true if all return true

not

public static BytesValidator not(BytesValidator validator)

This will negate the result of the passed validator

Parameters:

validator - to negate

Returns:

negated result
