Class SolanaAddress

java.lang.Object
com.codename1.crypto.solana.SolanaAddress
All Implemented Interfaces:
Comparable<SolanaAddress>
public final class SolanaAddress extends Object implements Comparable<SolanaAddress>
A Solana account address: 32 bytes, written in Base58. An address is either an Ed25519 public key or a program-derived address (PDA), which by construction is not on the curve and so has no private key.

      The address of 32 bytes, an Ed25519 public key or a PDA.

      • IllegalArgumentException: unless there are exactly 32 bytes

    • fromPrivateKey

      public static SolanaAddress fromPrivateKey(byte[] seed)
      The address of an Ed25519 private key (its 32-byte seed).

    • parse

      public static SolanaAddress parse(String base58)

      Reads a Base58 address.

      Throws
      • IllegalArgumentException: for text that is not Base58 or not 32 bytes

    • isValid

      public static boolean isValid(String base58)
      Whether text is a Base58 Solana address.

    • toBytes

      public byte[] toBytes()
      The address bytes, a copy.

    • isOnCurve

      public boolean isOnCurve()
      Whether the address is on the Ed25519 curve, which is to say it could have a private key. A program-derived address answers false.

    • createProgramAddress

      public static SolanaAddress createProgramAddress(byte[][] seeds, SolanaAddress programId)

      createProgramAddress: the address of seeds under a program, with no bump search.

      Throws
      • IllegalArgumentException: for more than 16 seeds, a seed over 32 bytes, or seeds whose hash falls on the curve

    • findProgramAddress

      public static SolanaAddress.ProgramAddress findProgramAddress(byte[][] seeds, SolanaAddress programId)
      findProgramAddress: the canonical PDA, searching the bump seed from 255 down.

    • createWithSeed

      public static SolanaAddress createWithSeed(SolanaAddress base, String seed, SolanaAddress owner)

      createWithSeed: the address SHA-256(base || seed || owner) that the System Program's *WithSeed instructions use.

      Throws
      • IllegalArgumentException: for a seed over 32 bytes

    • associatedTokenAddress

      public static SolanaAddress associatedTokenAddress(SolanaAddress wallet, SolanaAddress mint)
      The associated token account of a wallet for a mint under the SPL Token program.

    • associatedTokenAddress

      public static SolanaAddress associatedTokenAddress(SolanaAddress wallet, SolanaAddress mint, SolanaAddress tokenProgram)
      The associated token account of a wallet for a mint under a given token program, such as TOKEN_2022_PROGRAM.

    • toString

      public String toString()
      The Base58 form.
      Overrides:
      toString in class Object

    • equals

      public boolean equals(Object o)
      Description copied from class: Object
      Indicates whether some other object is "equal to" this one. The equals method implements an equivalence relation: It is reflexive: for any reference value x, x.equals(x) should return true. It is symmetric: for any reference values x and y, x.equals(y) should return true if and only if y.equals(x) returns true. It is transitive: for any reference values x, y, and z, if x.equals(y) returns true and y.equals(z) returns true, then x.equals(z) should return true. It is consistent: for any reference values x and y, multiple invocations of x.equals(y) consistently return true or consistently return false, provided no information used in equals comparisons on the object is modified. For any non-null reference value x, x.equals(null) should return false. The equals method for class Object implements the most discriminating possible equivalence relation on objects; that is, for any reference values x and y, this method returns true if and only if x and y refer to the same object (x==y has the value true).
      Overrides:
      equals in class Object

    • hashCode

      public int hashCode()
      Description copied from class: Object
      Returns a hash code value for the object. This method is supported for the benefit of hashtables such as those provided by java.util.Hashtable. The general contract of hashCode is: Whenever it is invoked on the same object more than once during an execution of a Java application, the hashCode method must consistently return the same integer, provided no information used in equals comparisons on the object is modified. This integer need not remain consistent from one execution of an application to another execution of the same application. If two objects are equal according to the equals(Object) method, then calling the hashCode method on each of the two objects must produce the same integer result. It is not required that if two objects are unequal according to the equals(java.lang.Object) method, then calling the hashCode method on each of the two objects must produce distinct integer results. However, the programmer should be aware that producing distinct integer results for unequal objects may improve the performance of hashtables. As much as is reasonably practical, the hashCode method defined by class Object does return distinct integers for distinct objects. (This is typically implemented by converting the internal address of the object into an integer, but this implementation technique is not required by the JavaTM programming language.)
      Overrides:
      hashCode in class Object

    • compareTo

      public int compareTo(SolanaAddress o)
      Orders addresses by their bytes, unsigned.
      Specified by:
      compareTo in interface Comparable<SolanaAddress>
      Returns:

      a negative integer if this instance is less than another; a positive integer if this instance is greater than another; 0 if this instance has the same order as another.

      Throws
      • ClassCastException: @throws ClassCastException if another cannot be converted into something comparable to this instance.
