Constructor & Destructor Documentation

◆ EUI48Sub() [1/3]

org.direct_bt.EUI48Sub.EUI48Sub ( )

Construct empty unset instance.

Definition at line 104 of file EUI48Sub.java.

Here is the caller graph for this function:

◆ EUI48Sub() [2/3]

org.direct_bt.EUI48Sub.EUI48Sub ( final String str ) throws IllegalArgumentException

Construct a sub EUI48 via given string representation.

Implementation is consistent with toString().

Parameters

str	a string of less or equal of 17 characters representing less or equal of 6 bytes as hexadecimal numbers separated via colon, e.g. "01:02:03:0A:0B:0C" , "01:02:03:0A" , ":" , "" .

See also: toString()

Exceptions

IllegalArgumentException if given string doesn't comply with EUI48

Definition at line 119 of file EUI48Sub.java.

Here is the call graph for this function:

◆ EUI48Sub() [3/3]

org.direct_bt.EUI48Sub.EUI48Sub	(	final byte	stream[],
		final int	pos,
		final int	len_
	)

Construct instance via given source byte array.

Definition at line 128 of file EUI48Sub.java.

Member Function Documentation

◆ clear()

void org.direct_bt.EUI48Sub.clear ( )

Method clears the underlying byte array b and sets length to zero.

The cached hash value is also cleared.

See also: clearHash()

Definition at line 184 of file EUI48Sub.java.

Here is the caller graph for this function:

◆ clearHash()

void org.direct_bt.EUI48Sub.clearHash ( )

Method clears the cached hash value.

See also: clear()

Definition at line 178 of file EUI48Sub.java.

◆ contains()

boolean org.direct_bt.EUI48Sub.contains ( final EUI48Sub needle )

Returns true, if given EUI48Sub needle is contained in this instance haystack.

If the sub is zero, true is returned.

Definition at line 246 of file EUI48Sub.java.

Here is the call graph for this function:

◆ equals()

final boolean org.direct_bt.EUI48Sub.equals ( final Object obj )

Definition at line 138 of file EUI48Sub.java.

Here is the call graph for this function:

Here is the caller graph for this function:

◆ hashCode()

final int org.direct_bt.EUI48Sub.hashCode ( )

Implementation uses a lock-free volatile cache.

See also: clearHash()

Definition at line 161 of file EUI48Sub.java.

◆ indexOf() [1/2]

static int org.direct_bt.EUI48Sub.indexOf	(	final byte	haystack_b[],
		final int	haystack_length,
		final byte	needle_b[],
		final int	needle_length
	)

static

Find index of needle within haystack.

Parameters

haystack_b	haystack data
haystack_length	haystack length
needle_b	needle data
needle_length	needle length

Returns: index of first element of needle within haystack or -1 if not found. If the needle length is zero, 0 (found) is returned.

Definition at line 199 of file EUI48Sub.java.

Here is the caller graph for this function:

◆ indexOf() [2/2]

int org.direct_bt.EUI48Sub.indexOf ( final EUI48Sub needle )

Finds the index of given EUI48Sub needle within this instance haystack.

Parameters

needle

Returns: index of first element of needle within this instance haystack or -1 if not found. If the needle length is zero, 0 (found) is returned.

Definition at line 236 of file EUI48Sub.java.

Here is the call graph for this function:

◆ scanEUI48Sub()

static boolean org.direct_bt.EUI48Sub.scanEUI48Sub	(	final String	str,
		final EUI48Sub	dest,
		final StringBuilder	errmsg
	)

static

Fills given EUI48Sub instance via given string representation.

Implementation is consistent with toString().

Parameters

str	a string of less or equal of 17 characters representing less or equal of 6 bytes as hexadecimal numbers separated via colon, e.g. "01:02:03:0A:0B:0C" , "01:02:03:0A" , ":" , "" .
dest	EUI48Sub to set its value
errmsg	error parsing message if returning false

Returns: true if successful, otherwise false
