Struct MethodDefinitionRow

Namespace
AsmResolver.PE.DotNet.Metadata.Tables
Assembly

Represents a single row in the method definition metadata table.

public struct MethodDefinitionRow : IMetadataRow, IReadOnlyList<uint>, IReadOnlyCollection<uint>, IEnumerable<uint>, IEnumerable, IEquatable<MethodDefinitionRow>

Constructors

MethodDefinitionRow(ISegmentReference, MethodImplAttributes, MethodAttributes, uint, uint, uint)

Creates a new row for the method definition metadata table.

public MethodDefinitionRow(ISegmentReference body, MethodImplAttributes implAttributes, MethodAttributes attributes, uint name, uint signature, uint parameterList)

Parameters

body ISegmentReference

The reference to the beginning of the method body.

implAttributes MethodImplAttributes

The characteristics of the implementation of the method body.

attributes MethodAttributes

The attributes associated to the method.

name uint

The index into the #Strings heap containing the name of the type reference.

signature uint

The index into the #Blob heap containing the signature of the method.

parameterList uint

The index into the Param (or ParamPtr) table, representing the first parameter that this method defines.

Properties

Attributes

Gets or sets the attributes associated to the method.

public MethodAttributes Attributes { readonly get; set; }

Property Value

MethodAttributes

Body

Gets a reference to the beginning of the method body.

public ISegmentReference Body { readonly get; set; }

Property Value

ISegmentReference

Remarks

This field deviates from the original specification as described in ECMA-335. It replaces the RVA column of the method definition row. Only the RVA of this reference is only considered when comparing two method definition rows for equality.

If this value is null, the method does not define any method body.

Count

Gets the number of elements in the collection.

public int Count { get; }

Property Value

int

The number of elements in the collection.

ImplAttributes

Gets or sets the characteristics of the implementation of the method body.

public MethodImplAttributes ImplAttributes { readonly get; set; }

Property Value

MethodImplAttributes

Remarks

These attributes dictate the format of Body.

this[int]

Gets the element at the specified index in the read-only list.

public uint this[int index] { get; }

Parameters

index int

The zero-based index of the element to get.

Property Value

uint

The element at the specified index in the read-only list.

Name

Gets or sets an index into the #Strings heap containing the name of the type reference.

public uint Name { readonly get; set; }

Property Value

uint

Remarks

This value should always index a non-empty string.

ParameterList

Gets or sets an index into the Param (or ParamPtr) table, representing the first parameter that this method defines.

public uint ParameterList { readonly get; set; }

Property Value

uint

Signature

Gets or sets an index into the #Blob heap containing the signature of the method. This includes the return type, as well as parameter types.

public uint Signature { readonly get; set; }

Property Value

uint

Remarks

This value should always index a valid method signature.

TableIndex

Gets or sets the index of the table that this row is stored in.

public TableIndex TableIndex { get; }

Property Value

TableIndex

Methods

Equals(MethodDefinitionRow)

Determines whether this row is considered equal to the provided method definition row.

public bool Equals(MethodDefinitionRow other)

Parameters

other MethodDefinitionRow

The other row.

Returns

bool

true if the rows are equal, false otherwise.

Remarks

When comparing both method bodies, only the RVA is considered in this equality test. The exact type is ignored.

Equals(object?)

Indicates whether this instance and a specified object are equal.

public override bool Equals(object? obj)

Parameters

obj object

The object to compare with the current instance.

Returns

bool

true if obj and this instance are the same type and represent the same value; otherwise, false.

FromReader(MetadataReaderContext, ref BinaryStreamReader, TableLayout)

Reads a single method definition row from an input stream.

public static MethodDefinitionRow FromReader(MetadataReaderContext context, ref BinaryStreamReader reader, TableLayout layout)

Parameters

context MetadataReaderContext

The reader context.

reader BinaryStreamReader

The input stream.

layout TableLayout

The layout of the method definition table.

Returns

MethodDefinitionRow

The row.

GetEnumerator()

Returns an enumerator that iterates through the collection.

public IEnumerator<uint> GetEnumerator()

Returns

IEnumerator<uint>

An enumerator that can be used to iterate through the collection.

GetHashCode()

Returns the hash code for this instance.

public override int GetHashCode()

Returns

int

A 32-bit signed integer that is the hash code for this instance.

ToString()

Returns the fully qualified type name of this instance.

public override string ToString()

Returns

string

The fully qualified type name.

Write(BinaryStreamWriter, TableLayout)

Writes the row to an output stream.

public void Write(BinaryStreamWriter writer, TableLayout layout)

Parameters

writer BinaryStreamWriter

The output stream writer.

layout TableLayout

The new layout of the table.

Operators

operator ==(MethodDefinitionRow, MethodDefinitionRow)

Determines whether two rows are considered equal.

public static bool operator ==(MethodDefinitionRow left, MethodDefinitionRow right)

Parameters

left MethodDefinitionRow
right MethodDefinitionRow

Returns

bool

operator !=(MethodDefinitionRow, MethodDefinitionRow)

Determines whether two rows are not considered equal.

public static bool operator !=(MethodDefinitionRow left, MethodDefinitionRow right)

Parameters

left MethodDefinitionRow
right MethodDefinitionRow

Returns

bool
