Method Detail

ByteSequence

public static dafny.DafnySequence<java.lang.Byte> ByteSequence(byte[] blob)

Parameters:

blob - The Java type for a blob can be an array of bytes.

Returns:

The Dafny Runtime type for a blob is a DafnySequence of Bytes.

See Also:

ToNative.Simple.ByteBuffer(dafny.DafnySequence<? extends java.lang.Byte>)

ByteSequence

public static dafny.DafnySequence<java.lang.Byte> ByteSequence(java.nio.ByteBuffer byteBuffer,
                                                               int start,
                                                               int limit)

Copy limit bytes from byteBuffer starting at start, and return them as a Dafny Runtime DafnySequence of Bytes.

Parameters:

byteBuffer - The Java type for a blob can be a ByteBuffer.

start - The index in the byteBuffer from which to start at.

limit - The number of bytes to copy.

Returns:

A DafnySequence of Bytes, containing the copied bytes.

See Also:

ToNative.Simple.ByteBuffer(dafny.DafnySequence<? extends java.lang.Byte>)

ByteSequence

public static dafny.DafnySequence<java.lang.Byte> ByteSequence(java.nio.ByteBuffer byteBuffer)

A convenience function for converting all the bytes from a ByteBuffer.

Note: Regardless of the buffer's mark, position, or capacity, this will return the bytes from 0 till limit.

Parameters:

byteBuffer - The Java type for a blob can be a ByteBuffer.

Returns:

A DafnySequence of Bytes, containing the bytes in the byteBuffer, starting from 0 until the buffer's limit.

See Also:

ToNative.Simple.ByteBuffer(dafny.DafnySequence<? extends java.lang.Byte>)

Double

public static dafny.DafnySequence<java.lang.Byte> Double(java.lang.Double aDouble)

At this time, Dafny does not have an idiomatic Double type in the language or any standard library.

Instead, the Double is serialized into bytes, which are then wrapped as a DafnySequence of Bytes.

Note: This serialization is NOT guaranteed to be consistent among different Dafny Runtimes or even native distributions.

Parameters:

aDouble - The Java type for a double can be a Double.

Returns:

A DafnySequence of Bytes containing the serialization of the aDouble.

See Also:

ToNative.Simple.Double(dafny.DafnySequence<? extends java.lang.Byte>)

CharacterSequence

public static dafny.DafnySequence<java.lang.Character> CharacterSequence(java.lang.String aString)

Parameters:

aString - The Java type for a String is String.

Returns:

The Dafny Runtime type for a String is A DafnySequence of Characters.

See Also:

ToNative.Simple.String(dafny.DafnySequence<? extends java.lang.Character>)

CharacterSequence

public static dafny.DafnySequence<java.lang.Character> CharacterSequence(java.util.Date timestamp)

At this time, Dafny does not have an idiomatic Timestamp or Date type in the language or any standard library.

Instead, the Timestamp is serialized as seconds from epoch, as a string, which is than wrapped as a DafnySequence of Characters.

Parameters:

timestamp - The Java type for a Smithy timestamp can be Date.

Returns:

A DafnySequence of Characters containing the serialization of the timestamp.

See Also:

ToNative.Simple.Date(DafnySequence)

CharacterSequence

public static dafny.DafnySequence<java.lang.Character> CharacterSequence(java.time.Instant timestamp)

At this time, Dafny does not have an idiomatic Timestamp or Date type in the language or any standard library.

Instead, the Timestamp is serialized as seconds from epoch, as a string, which is than wrapped as a DafnySequence of Charters.

Parameters:

timestamp - The Java type for a timestamp can be Instant.

Returns:

A DafnySequence of Characters containing the serialization of the timestamp.

See Also:

ToNative.Simple.Instant(DafnySequence)

DafnyUtf8Bytes

public static dafny.DafnySequence<java.lang.Byte> DafnyUtf8Bytes(java.lang.String aString)

Dafny can be configured to represent Strings in an encoding OTHER THAN UTF-8.

(Until recently, it only supported UTF-16.)

Regardless of how the Dafny Compiler is configured, this method can be used to reliably convert a Java String to a DafnySequence of UTF-8 Encoded bytes.

Parameters:

aString - The Java type for a String is String

Returns:

A DafnySequence of Bytes containing aString as UTF-8 Encoded Bytes.
