Methods in com.pi4j.crowpi.components.internal.rfid that throw RfidException

Modifier and Type	Method	Description
RfidCard	MFRC522.initializeCard()	Selects a single PICC and transitions it from READY to ACTIVE state, then returns an appropriate RfidCard instance.
protected void	MFRC522.mifareAuth(MifareKey key, byte blockAddr, RfidCardUid uid)	Authenticates the sector to which the specified block belongs for MIFARE PICCs.
protected byte[]	MFRC522.mifareRead(byte blockAddr)	Reads the specified block from a MIFARE PICC using PiccCommand.MF_READ.
protected void	MFRC522.mifareWrite(byte blockAddr, byte[] dataBuffer)	Writes the specified amount of data using PiccCommand.MF_WRITE to a MIFARE PICC.
protected byte[]	Mifare1K.readBytes()	Reads all available blocks from the card and returns a byte array.
protected abstract byte[]	RfidCard.readBytes()	Reads all available blocks from the card and returns a byte array.
Object	RfidCard.readObject()	Reads a single Java object from the card without casting the result into a more-specific type.
<T> T	RfidCard.readObject(Class<T> type)	Reads a single Java object from the card by deserializing a GZIP-compressed byte stream previously written onto the card.
protected RfidCardUid	MFRC522.select()	Selects a single PICC by executing the ANTICOLLISION and SELECT procedure according to ISO 14443.
void	MFRC522.uninitializeCard()	Uninitializes the currently active card by sending it back into HALT state and stopping encrypted communication.
protected void	Mifare1K.writeBytes(byte[] data)	Writes the given data to the card, using as many blocks as needed.
protected abstract void	RfidCard.writeBytes(byte[] data)	Writes the given data to the card, using as many blocks as needed.
void	RfidCard.writeObject(Object data)	Stores a single Java object onto the card by serializing the passed object and writing a GZIP-compressed byte stream.
