Package com.pnfsoftware.jeb.util.encoding.cbor

Class CborType

java.lang.Object
com.pnfsoftware.jeb.util.encoding.cbor.CborType
public class CborType extends Object
Represents the various major types in CBOR, along with their .

The major type is encoded in the upper three bits of each initial byte. The lower 5 bytes represent any additional information.

  • Method Details

    • getName

      public static String getName(int mt)
      Returns a descriptive string for the given major type.
      Parameters:
      mt - the major type to return as string, values from [0..7] are supported.
      Returns:
      the name of the given major type, as String, never null.
      Throws:
      IllegalArgumentException - in case the given major type is not supported.

    • valueOf

      public static CborType valueOf(int i)
      Decodes a given byte value to a CborType value.
      Parameters:
      i - the input byte (8-bit) to decode into a CborType instance.
      Returns:
      a CborType instance, never null.

    • equals

      public boolean equals(Object obj)
      Overrides:
      equals in class Object

    • getAdditionalInfo

      public int getAdditionalInfo()
      Returns:
      the additional information of this type, as integer value from [0..31].

    • getMajorType

      public int getMajorType()
      Returns:
      the major type, as integer value from [0..7].

    • hashCode

      public int hashCode()
      Overrides:
      hashCode in class Object

    • isBreakAllowed

      public boolean isBreakAllowed()
      Returns:
      true if this type allows for an infinite-length payload, false if only definite-length payloads are allowed.

    • isEqualType

      public boolean isEqualType(CborType other)
      Determines whether the major type of a given CborType equals the major type of this CborType.
      Parameters:
      other - the CborType to compare against, cannot be null.
      Returns:
      true if the given CborType is of the same major type as this CborType, false otherwise.
      Throws:
      IllegalArgumentException - in case the given argument was null.

    • isEqualType

      public boolean isEqualType(int encoded)
      Determines whether the major type of a given byte value (representing an encoded CborType) equals the major type of this CborType.
      Parameters:
      encoded - the encoded CBOR type to compare.
      Returns:
      true if the given byte value represents the same major type as this CborType, false otherwise.

    • toString

      public String toString()
      Overrides:
      toString in class Object
