equals back to summary

equals	back to summary
public boolean equals(final Object o) Overrides nonapi.io.github.classgraph.fastzipfilereader.ZipFileSlice.equals. Doc from java.lang.Object.equals. Indicates whether some other object is "equal to" this one. The `equals` method implements an equivalence relation on non-null object references: It is reflexive: for any non-null reference value `x`, `x.equals(x)` should return `true`. It is symmetric: for any non-null 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 non-null 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 non-null 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 objects is modified. For any non-null reference value `x`, `x.equals(null)` should return `false`. An equivalence relation partitions the elements it operates on into equivalence classes; all the members of an equivalence class are equal to each other. Members of an equivalence class are substitutable for each other, at least for some purposes. Parameters o:Object the reference object with which to compare. Returns:boolean `true` if this object is the same as the obj argument; `false` otherwise. Annotations @Override

public boolean equals(final Object o)

Overrides nonapi.io.github.classgraph.fastzipfilereader.ZipFileSlice.equals.

Doc from java.lang.Object.equals.

Indicates whether some other object is "equal to" this one.

The equals method implements an equivalence relation on non-null object references:

It is reflexive: for any non-null reference value x, x.equals(x) should return true.
It is symmetric: for any non-null 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 non-null 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 non-null 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 objects is modified.
For any non-null reference value x, x.equals(null) should return false.

An equivalence relation partitions the elements it operates on into equivalence classes; all the members of an equivalence class are equal to each other. Members of an equivalence class are substitutable for each other, at least for some purposes.

Parameters

o:Object: the reference object with which to compare.

Returns:boolean

true if this object is the same as the obj argument; false otherwise.

getManifestValue	back to summary
private static Map.Entry<String, Integer> getManifestValue(final byte[] manifest, final int startIdx) Extract a value from the manifest, and return the value as a string, along with the index after the terminating newline. Manifest files support three different line terminator types, and entries can be split across lines with a line terminator followed by a space. Parameters manifest:byte[] the manifest bytes startIdx:int the start index of the manifest value Returns:Map.Entry<String, Integer> the manifest value

getManifestValue

back to summary

private static Map.Entry<String, Integer> getManifestValue(final byte[] manifest, final int startIdx)

Extract a value from the manifest, and return the value as a string, along with the index after the terminating newline. Manifest files support three different line terminator types, and entries can be split across lines with a line terminator followed by a space.

Parameters

manifest:byte[]: the manifest bytes
startIdx:int: the start index of the manifest value

Returns:Map.Entry<String, Integer>

the manifest value

hashCode back to summary

hashCode	back to summary
public int hashCode() Overrides nonapi.io.github.classgraph.fastzipfilereader.ZipFileSlice.hashCode. Doc from java.lang.Object.hashCode. Returns a hash code value for this object. This method is supported for the benefit of hash tables such as those provided by `java.util.HashMap`. 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` 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` 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 hash tables. Returns:int a hash code value for this object Annotations @Override
